====================
Intel Wired LAN Driver Updates 2026-04-14 (ice, i40e, iavf, e1000e)

Grzegorz updates the logic for adjusting the PTP hardware clock on E830,
fixing a bug that prevented adjustments below S32_MAX/MIN nanoseconds.

Grzegorz and Zoli update the PCS latency settings for E825 devices at 10GbE
and 25GbE, improving the accuracy of timestamps based on data from
production hardware.

Michal Schmidt fixes a double-free that could happen if a particular error
path is taken in ice_xmit_frame_ring().

Guangshuo fixes a double-free that could happen during error paths in the
ice_sf_eth_activate() function.

Paul Greenwalt fixes the PHY link configuration when the link-down-on-close
driver parameter is enabled and new media is inserted.

Paul Greenwalt fixes the ICE_AQ_LINK_SPEED_M macro for 200G, enabling 200G
link speed advertisement.

Keita Morisaki fixes a race condition in the ice Tx timestamp ring cleanup,
preventing a possible NULL pointer dereference.

Kohei Enju fixes a potential NULL pointer dereference in ice_set_ring_param().

Kohei Enju fixes i40e to stop advertising IFF_SUPP_NOFCS, when the driver
does not actually support the feature.

Petr fixes the VLAN L2TAG2 mask when the iAVF VF and a PF negotiate use of
the legacy Rx descriptor format.

Matt fixes the unrolling logic for PTP when the e1000e probe fails after
the PTP clock has been registered.

 **A note to stable backports**

  The patches [7/12] ("ice: fix race condition in TX timestamp ring
  cleanup") and [8/12] ("ice: fix potential NULL pointer deref in error
  path of ice_set_ringparam()") must be backported together. Otherwise the
  fix in patch 8 will not work properly.
